Ground S-Band Hybrid AESA Antenna, Moving from Concept to Measurement Results of the Prototype

Abstract

The contribution talks about the application of AESA technology for telemetry ground antennas. The AESA concept we are proposing is a 1-axis electronically steerable antenna (elevation axis), while the azimuth axis remains mechanically driven. The design will lead to a 1m² antenna, dedicated to short - medium range telemetry, with potential high target dynamics. This paper introduces the concept and details the design with the first mock-up, which was manufactured and measured. The results present a very important knowledge in the establishment of phase controls for beam-steering, and in the control of the axial ratio. Then, this document focuses on the development of a complete prototype for an evaluation at the end of 2022.
